GRAPPL E FOR LUBRlCATlNG-PADS.

SPECIFICATION forming part of Letters Patent N 0. 709,604, dated September 23, 1902.

Application filed February 24, 1902. Serial No. 95,436. (No model.)

To (bi/Z whom, it may concern:

Be it known that I, J OHANNES LOESEWITZ, a citizen of the German Empire, residing at Witten-on-the-Ruhr, in the Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Grapples for Lubricating-Pads; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to grapples for engaging the supports of lubricating-pads used in railroad axle-boxes; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a longitudinal section through a lubricating-pad, its support, and grapple. Fig. 2 is a cross-section through the same. Fig. 3 is a plan view of the grapple, showing also a portion of the support.

The lubricating-pad and its support are of any approved construction used in railway axle boxes. The upper plate a is curved and supports the lubricating-pad A, which bears against the axle. The lower plate 01 rests on the bottom of the axle-box. Springs e are arranged between the said plates and press the pad upward against the axle. For convenience in removing the pad and its support the upper plate is provided with eyesf and the lower plate with eyes 9.

Two crossed and pivoted U-shaped handles a and b are provided as a grapple for the pad and its support. The handle a has short outwardly-projecting pivots a at its free ends which engage with the eyes g, and the handle I) has short inwardly-projecting pivots Z) at its free ends which engage with the eyes f. The handles a and b are sprung laterally out of engagement with the eyes when the grapple is to be disengaged from the pad-support. The handle I) has the middle parts of its side portions bent around to form eyes i, and the handle ahas the middle parts of its side portions bent double to form projecting pivots 7c. The pivots 7c are pivoted in the eyest'and permit the arms of the handles to be sprung laterally in line with the pivots a and b.

When the pad is to be removed from the axle-box, the looped ends of the handles are pressed toward each otherin the direction of the arrows in Fig. 1, and the grapple is then withdrawn from the axle-box together with the pad and its support. Each pad may be provided with a grapple, and the grapple may be left in the axle-box with the pad, if desired. A single grapple can, however, be used for a number of pads, if desired, or if there is not room for it in the axle-box.

WVhat I claim is- 1. A pair of crossed U shaped handles having short laterally-projecting pivots at their free ends, the side portions of the said handles being free to spring laterally, and means for pivotally connecting the middle parts of the side portions of the said handles, substantially as set forth.

2. A pair of crossed and pivoted U-shaped handles formed of bent rods having laterallyprojecting pivots at their free ends, the side portions of one of the said handles being bent around to form eyes 2', and the side portions of the other said handle being bent double to form projecting pivots 7a which engage with the said eyes, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

J OHANNES LOESEWITZ.
